IMPROVEMENT IN SPINNING-MACHINES.

Specification forming part of Letters Patent No. 145,322, dated December 9, 1875i; application iied July 11, 1873.

To all whom fit may concern:

. Be it known that we, CHAUNcEYWILLrAMs, SAMUEL M. VILLIAMS, and HENRYM. WIL- LIAMS, of Coldwater, in the county ofBranch and State of Michigan, have invented a new and useful 'Improvement in a Spinning- Machine;and we do declare that the following is a true and accurate descriptionthereof, reference be-r ing had to the accompanying drawings, and to theletters of reference marked thereon, and heilig a part of thisspecification, in which- Figure l, Sheet 1,. is a perspective view. Fig.2, Sheet 2, is an` elevation of the lefthand end of Fig. l. Fig. 3,Sheet 3, is a plan of the top. Fig. 4, Sheet 4, is a crosssectionA onthe line :v x in Fig. 1. Fig. 5, Sheet 5, is an enlc rged longitudinalsection of a twisting-tube taken through the line y y in Fig. 3. Fig. 6is across-section on z z in Fig. 5. Fig. 7 is an end view of thetwisting-nut on the end of the tube. Fig. Sis an enlarged verticalsection of aspinning-ring and bobbin on its spindle. Fig. 9 is a similarsection of the bobbin.v Fig. 10 is a view of the slotted vquadrant-armwhich carries the change-wheel in the feed-train. l

The nature of this invention relates to an improvement in machines inwhich woolen rovings may be spun into yarn and wound upon bobbinscontinuousl f; and it consists in the peculiar construction andarrangement of the mechanism for raising and lowering the platform whichcarries the bobbin-spindles also, in the peculiar construction of saidtwisting-tubes, provided with changeable crossslotted nuts, antL inother arrangements. of devices, as hereinafter described the arrangementof the whole being such that the tubes twist the rovings suiiiciently togive them the required strength to resist the tension put upon themWhile being subsequently spun, the twist so given being taken out andreversed by the spinning-rings,which wind them as fast as spun upon thebobbins.

In the drawings, Al represents the frame of our spinner, in' the lowerright-hand en'd of which a driving-shaft, B, is journaled, which shaft,besides the usual fast and loose pulleys a af, is provided with a largecone-pulley, B1, from which motion is given to a drum, C, journaledacross the back part of the frame, by a belt, B2, passing around a cone,Cl, on the end of said drum. D is a spii'ining-ring bearin g, preferablyof metal, made in two parts, D D, resting horizontally upon bracketsprojecting from the front of the frame, to which the inner part, D, ispermanentlyT secured, the front half being secured to the part D bybolts b passing' through both, with nuts 011 their front ends, by whichthe twoparts may be brought together with any desired degree ofcompression. These parts are internally channeled, and in them aredrilled vertical bearings, at regular distances, for the hollowspinning-rings E, Figs. 4 and 8, havingl jour* nals turned down on theirends, which rotate in the bearings halved in the upper and lower sidesof the parts D D. The part D has an opening behind each bearing throughwhich a cord, C2, passes with a quarter-turn around each ring, which isgrooved around its middle to receive the said cord from the drum C, andeach ring is provided with an eye c, at its top end, through which theyarn passes. Below the ring-bearing brackets, another pair of bracketsprojects from the lower part of the frame, which support the guides d d,whose tops are secured to the brackets above, and upon each slides across-head, f, Fig. 2, to which is secured a two-part spindle-bearing, FF', in which the lower ends of the bobbinspindles G are journaled, thektwo yparts F F being secured together by three transverse bolts, c,whose nuts may be screwed up to im pede the free rotation of thespindles, whose bearings may be of wood or metal, as preferred. I arethe bobbins, each secured upon thc taperingspindle, and playing freelythrough the opening 1n the spinning-ring E above, as the bearing F F israised or lowered, which is effected in the following manner: At theside of each cross-head fis pivoted the lo wer end of a connecting-rod,I, whose upper end is pivoted in a slot, g, of a lever, I, by a pin,"fi,the said lever being pivoted back of the slot to the sido of one of thefront posts of the frame.

To the rear end of each lever is pivoted a connecting-rod, I2, whoselower end is strapped to an eccentric, H, at each end of a shaft, J,journaled in a bracket projecting up from one of the lower girts of theframe. This shaft J is slowly rotated by its bevel-pinion K meshing witha bevel-gear, K1, mounted on a vshort vertical shaft, K2, journaled insuitable bearings, and carrying a horizontal wormgear, K3, rotated by aworm, K4, on the inner end of the driving-shaft B, whose rotation thuscauses the rise and fall ofthe spindle-bearings. When the bobbins areempty, and to be wound, their bases are flush with the tops of therings, through which they fall their own length, and rise again at eachrevolution of the eccentrics, which is sufficient to ll them with onelayer of yarn. This would, however, wind them with yarn into the shapeof cylinders; and, to give them the shape required, it is necessary thatthe bobbins should move slowly at mid-height, and faster at top andbottom, and to this end we employ the following mechanism Near theleft-hand end of the shaft J we key a pinion, L, which, through a trainof spur-gears,

L1 L2 L3, communicates aslow motion to a shaft,

M, journaled racross the lower girts of the frame, carrying at each enda wiper-cam, N, upon which rests the horizontal arm of a bellerank, 0,pivoted to the side of a front post in the frame. The upper part ofveach bell crank is a curve or segment, and has a slot, g', into whichone end of the pin t' of the connecting-rod I projects. The wipers N areso timed. with relation to the throw of the eccentrics that the pin 11is thrown forward in thev slots g to give it a greater radius, andconsequently a more rapid vertical movement to the spmdle-bearin g,while approaching or receding from the ends of the bobbins to themiddle,T

andaslower movement from the ends toward the middle of the bobbins, byreducing the radius of said pin in the slot g, thereby causing more yarnto be wound upon the middle, and less at the ends of the bobbins.

The feeding and drawing rolls are at the top of the machine, and tooperate them we employ the following mechanism: 0n the shaft B there isa pulley, Q, one edge of which is seen in FiO. l, from which a crossedbelt, Q, is carried around a pulley, R, mounted on a shaft, R1,journaled in and projecting inwardly from the right top girt of theframe, and carrying a pinion, R2, which meshes with and gives motion toa spur-gear, R3, whose shaft is journaled in a bracket on top of saidgirt, with a bevel-pinion, R4, and a spur-pinthereof, whereby anydesired pressure may be exerted by the elastic rollers Z upon -the upperrollshaft on the metallic rollers l1 mounted on the lower roll-shaft,the yarn passing between and being drawn forward by the said rollers.yThe pinion R5 meshes with a change-pinion, U, mounted on a studprojecting from the slotted quadrant Y, Fig. 10,'bolted to the side ofthe top girt, and meshes with a changewheel, U,'mounted on a stud at thelower end of said quadrant, which in turn meshes with the pinion U2 onthe end of the lower feed-roll shaft YV journaled in the standards J"-boxes sliding in the same standards, and earries a series of elasticrollers, l2, while the lower roll-shaft carries a series of inelasticrollers, Z3, upon which the rollers Z2 may be caused to press byscrewing down the capbearings of the upper roll through the setscrews kin the standards j. Near the end of the lower roll-shaft W is apinion,U-3, which meshes with the gear U4, which vdrives a spurwheel,U5, at the end of a shaft, X, which carries the roving-drum X1 at theback of the the machine, thence each through an eye, c, on

the spinning-ring E, to the bobbin. J ust before passing between thedrawing-rolls the roving passesV through a twisting-tube, Y,

journaled in a pillar, Y2, on the frame-top,

and to which an axial rotation is imparted by a quarter-turn endlesscord, n, from a-drum, Z, journaled in brackets below, which drum isdriven by a belt, Z2, passing around a pulley, Z2, on its end from apulley, C3, on the end of the drum C. The twisting-tubes may be eithercylindrically bored and tapered at the rear end ofthe bore, as shown inFig. 5, or be tapered from end to end, as preferred. In the end of eachis screwed a nut, Y1, having a cruciform slot through which the yarnmust pass 5 these nuts may have different sizes of slots for twistingcoarse and -iine rovings. The feed-rolls have a slower movement than thedrawing-rolls, while the spinning-rings have a higher speed than either.The relative speeds of the latter and of the twistingtubes areunchangeable, but, by means of the quadrant Y and changing the pinions Uand U1, the speed of the feed-rolls may be changed so as to put agreater or lesser tension onthe rovings the less speed given thefeed-rolls the greater the tension will be, and vice versa. The speed ofthe machine, as a whole, may be varied by shifting the driving-belt B2on the cone-pulleys. The ends of the rovings being passed between thefeed-rolls, they are thence passed through the twistingtubes, thencethrough the eyes c of the spinning-rings E, and tied to thebobbin-bases. The machine W is the top feed roll shaft, journaled in Ybeing in motion, the tube-s twist the rovings suiiiciently to enablethem to stand the tension put on them by the drawing-rolls, theirdiameters being correspondinglyreduced. The twist put in the rovin gs istaken out by the spinningrin gs, which rotate in the oppositedirections, Winding the yarn `spun upon the bobbins, the spindles beingslowly rotated withthe vbobbins by being cramped in their bearings tosuch 'an' extent that about two-thirds of the tension is put in by thedrawing-rolls, while the remainder of the tension is put in by thespindle -bearings Each rotation of a' spinnin g-ring puts a twist in theyarn and lays a coil around the bobbin, while each time the eccentricsrotate to raise and lower the bobbins 'a layeris wound upon them. Onerota. `tion of the wiper-cams is vsufficient to ll the bobbins and givethem the necessary swell at the middle. When a spool of rovings is runoff, another one, filled and lying in the sockets at the top of thespool-bracket, replaces the empty one. The ends of the royings, beingconnected with' those passing through the feed-rolls, are continuous.When a bobbin is wound full the motion of its spinning-ring E isarrested by a brake until it can be removed and replaced in thefollowing manner: o is a brake-block, sliding in an opening through therear side of the bearing D at the back of each ring E. p is a shaft,secured in brackets projecting from the frame below and behind thebearing D, and on this shaft are hung the bellcrank treadles q, each ofwhich maybe depressed by the foot, when its top end will force thekbrake block inward against the ring E to arrest its motion.
